TERMINAL CONNECTION.

Application filed September at, 1927. Serial 170,221,766.

This invention relates to a terminal connection and has relation moreparticularly to a device of thiskind particularly-adapted for use withthe terminal of a storage battery or the like, and it is an object ofthe invention to provide a connection of this character which can beeffectively applied.

' or removed.

Another object of the invention is to-pro- 1 vide a device of this kindadapted to sur-- round or embrace a batter terminal post together withmeans for e ectively clamping the connection to the post and in a mannerwhereby :it may be easily released.

The invention. consists in' thedetails of construction, and in thecombination and arrangement of the several parts of my im-' rovedterminal connection whereby certain lmportant advantages are attainedand the device rendered simpler, less expensive and.

otherwise more convenient and advantaeous for use, as will behereinafter more ull set forth. y I

T e novel features of my invention will hereinafter be definitelyclaimed.

In order that m invention may better understood, will now proceed to de:

scribe the same with reference to the accom panying drawing, wherein a tFigure 1 is a view'in perspective of a termma connection constructed inaccordance with an embodiment of my invention in applied position;

Figure 2 is a view in top plan of the con- I, nection as hereindisclosed unapplied;

Fi ure 3 is aview'similar to Figure 2.

' showing the locking member in release position;

structure as illustrated in Figure 2. As disclosed in the accompanyingdrawing, my improved terminal connection comprlsesa split annular memberM providing 'the jaws 1 adapted to receive therebetween" I a terminalpost 'P and to be effectively clamped thereto in a manner to behereinafter described. The member M, as herein disclosed, at its baseportion is provided with an outstanding slip barrel 2 in which 5" anextremit of an electrical conductor 3 is adapted to e securely engaged.-

The outer or free end portions of the jaws 1 are continued b theoutstanding and substantially paralle blocks 4 preferably of athicknessmaterially greater than the thickness of the major portions ofthe jaws 1.

be the,

' Figure 4 is a view in side elevation of the The outer faces of saidblocks 4 are provided thereacross with the grooves or channels 5preferably substantially V-shaped in cross section.

Freely disposed throu h the blocks 4 at substantially the longitu inalcenters of the grooves 5 is an elongated shank 6 provided at one endwith a head 7 and having threaded upon its opposite end portion a nut 8,said nut having contact from without with a washer 9 freely mounted onthe shank 6 and of a diameter to bridge the adjacent groove 5 in orderto have firm and close contact with the""outer face of the adjacentblock 4. The arms 1 possess a certain degree of inherent resiliencyserving to normally maintain the blocks 4 spaced apart a distancewhereby the aws 1 may be readily and freely engaged or released from thepost P and permitting said jaws to be moved equilateral triangle withits apex disposed,

toward the adjacent block 4 so that when the head '10 is disposedtransversely of such block the groove 5- of said block 4 will readilyreceive the apex portion of the head 10, thus permitting sufiicientseparating movement of the blocks and the jaws 1 when it is desiredto'release orfree the connection from the post P.

With the head 10 in its transverse position i with respect to theadjacent block 4 and the jaws 1 properly engaged with the post P, uponsubstantially a quarter turn being given to the head 10 the same willreadily ride out, of the groove 5 and b contact with the head 7 willforce the bloc s 4 together with the jaws 1 one toward the other intoeffective clamping engagement with the post P.

One end portion of the head 10 preferably at its back is continued toprovide an elongated handle member or lever 11 which will facilitate therequisiteturning movement of the head 10. c

It is to be noted that the blocks 4 are in duplicate. By this means theassembly of the connection is facilitated as the head 10 will operatewith the same convenience and facility in connection with either one ofsaid blocks.

From the foregoing description it is thought to be obvious that aterminal connection constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with whichit may be assembled and operated, and it will also beobvious that my invention is susceptible of some change and modificationwithout departing from the principles and spirit thereof and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

1 claim 1. A terminal connection comprising a pair of jaws adapted toreceive a terminal post therebetween, blocks carried by the outer endsof the jaws, a shank freely disposed through the blocks, a transverselydisposed groove provided in the outer face of each of the blocks, saidshank being disposed through said grooves, means carried by the shankfor contact with the outer face of one of the blocks, an enlargementcarried by the opposite end portion of the shank, a head freely mountedon the shank between the enlargement of the shank and the second block,said head when in one position extending within the groove of theadjacent block to permit separating movement of the blocks and jaws,said head when turned to a position angular to the groove forcing theblocks and jaws one toward the other.

2. A terminal connection comprising a pair of jaws adapted to receive aterminal post therebetween, blocks carried by the outer ends of thejaws, a= shank freely disposed through the blocks, one of said blockshaving a groove disposed across the outer face thereof, said shank beingdisposed 4 through said groove, means carried by an end portion of theshank for contact with the outer face of the second block, anenlargement carried by the opposite end portion of the shank, a headfreely mounted on the 60 shank between the enlargement of the shank andthe block provided with the groove, said head when in one positionextending within the groove of the adjacent block to permit separatingmovement of the blocks and jaws, said head when turned to a positionangular to the groove forcing the blocks and jaws one toward the other.

3. A terminal connection comprising a' pair of jaws adapted to receive aterminal post therebetween, blocks carried by the outer ends of thejaws, a shank freely disposed through the blocks, one of said blockshaving a groove disposed across the outer face thereof, said shank beingdisposed through said roove, means carried by an; end portion 0 theshank for contact with the outer face of the second block, anenlargement carried by the opposite end portion of the shank, a headfreely mounted on the shank between the enlargement of the shank and theblock provided with the groove, said head when in one osition extendingwithin the groove of t e adjacent block to permit separating movement ofthe 7 blocks and jaws, said head when turned to a position angular tothe groove forcing the blocks and jaws one toward the other, said headin cross section being substantially triangular with its apex disposedtoward the ad acent block to of said block. v 7

In testimony whereof I hereunto afiix my signature.

be received in the groove JAMES H. EATON.
